A Prince William County police officer was shot and killed Saturday evening on her first day on the street when she responded to a call about a possible domestic matter, authorities said.

Two other officers were shot and wounded.

The slain officer was identified by police as Ashley Guindon. No information was available about the other two. All three were flown by helicopter to Inova Fairfax Hospital.

One person was taken into custody in connection with the shooting, but no information about the individual had been released as of late Saturday.

The gunfire broke out about 5:30 p.m. in the 13000 block of Lashmere Court, a relatively short residential street in the Woodbridge/Lake Ridge area south of the county government administration center.

Guindon was identified in reference material as a graduate of ­Embry-Riddle Aeronautical University in Daytona Beach, Fla., who held a bachelor’s degree in aeronautics. She served in the U.S. Marine Corps Reserve and had relatives in law enforcement.

Online information indicated that she graduated from Merrimack high school in New Hampshire in 2005, and had held a license to fly historical aircraft. A source familiar with her Marine Corps service said she held the rank of corporal and was assigned to a unit at Bolling Air Force Base involved with sending home the remains of fallen Marines.

The slain officer had been assigned to patrol duty in the eastern part of the Virginia suburban county. A police tweet indicated that she had been sworn in only Friday.

The nature of the domestic disagreement that brought the officers to the site was not made clear.

However, Corey A. Stewart (R-At Large), who is chairman of the Board of County Supervisors, said a woman apparently was killed in connection with the incident.

Sgt. Jonathan Perok, a police spokesman, said he could not confirm that account.

A woman who lives on Lashmere Court said she was visiting a neighbor and heard sounds but did not think gunfire could have broken out on her quiet and close-knit street.

“We never thought it could be shots,” said Maritza Gutierrez.

She said she heard “Boom, boom, boom. Something like that.” It was, she said, “Very quick.”

Then emergency personnel arrived, and she looked outside to determine what had happened.

She said she saw someone, apparently one of the three wounded officers, lying on a lawn.

Emergency personnel were administering aid, and it appeared that the officer’s uniform had been removed to facilitate the treatment.

Finally, Gutierrez said, the patient was taken from the lawn to an ambulance.
